Xcode Number pad with decimal error

Question

In xcode when I turn on the decimal pad keyboard option in the .xib for my textfield, and I run the application, I receive this error:

Jun 13 01:22:38 Nicholas-Gibsons-iPhone Quick Utilities[1009] <Error>: 
CGContextSetFillColorWithColor: invalid context 0x0. This is a serious error. This 
application, or a library it uses, is using an invalid context  and is thereby 
contributing to an overall degradation of system stability and reliability. This notice is 
a courtesy: please fix this problem. It will become a fatal error in an upcoming update.

If you have any idea what this really means, you would be a lot of help! Thanks so much!

Answer 1

try the following :

textField.keyboardType = UIKeyboardTypeDecimalPad;

Answer 2

Check to see if you are using context anywhere - if so rename it anywhere it occurs.
